    Syed Saad B Qasim, Dena Ali, Abdul Samad Khan, Shafiq Ur Rehman, Abid Iqbal, Jagan Kumar Baskaradoss.
      Background: This bibliometric analysis is aimed at reviewing the research pattern on the use of silver diamine fluoride (SDF) in dentistry using various citation metrics.Methods: A well-curated search was conducted on Elsevier's Scopus database for the relevant literature on SDF published between 1969 and 2021. Bibliographic information such as information related to citations, bibliographic data, abstracts, keywords, and other relevant information was extracted using different combinations of keywords ("silver diamine fluoride" OR "Silver Diamine Fluorides" OR "Diamine Fluoride" OR "Silver Fluoride"). Analysis and visualization of the selected documents and related data were performed using various tools and software including MS Excel, MS Access, Bibexcel, VOS viewer, Biblioshiny, and Gephi. VOS Viewer was utilized for the Graph Modeling Language (GML) to generate graphical representations of the data. Furthermore, network graphs were generated to assess the various associations between research themes, countries, organizations, authors, journals, and citations.
    Results: The initial search yielded 662 documents, of which 410 were chosen for analysis. 252 records were deemed irrelevant. The chosen records consisted of journal articles (n = 351), conference papers (n = 14), book chapters (n = 1), and review articles (n = 44). The results showed that there was an upward trend in the research on SDF, and a substantial increase was observed in the citation index after 2014. Researchers from the United States of America, Hong Kong, and Japan were the top contributors, with organizations and authors from the Faculty of Dentistry, University of Hong Kong, leading the way in citations and productivity.
    Conclusion: The bibliometric analysis provides valuable information regarding the total number of publications on SDF and their citation details. It also identifies the leading countries and organizations involved in the research on SDF and provides a comprehensive analysis of the research trends related to SDF.

    Bibliometric analysis of global research trends on male osteoporosis: a neglected field deserves more attention.
    Haiyang Wu, Zaijie Sun, Linjian Tong, Yulin Wang, Hua Yan, Zhiming Sun.
      We analyzed the knowledge structure, current status, and future directions of 3243 publications on male osteoporosis by employing bibliometric analysis. Our results indicated that Osteoporosis International was the most influential journal in this field. And the study of epidemiology and risk factors has been recognized as a hot research topic in recent years. This study also calls for more attention to be given on male osteoporosis research.INTRODUCTION: Male osteoporosis is increasing as a serious health problem worldwide with the aging of population. However, a comprehensive understanding of the current status and future trends in this field is lacking to date. The goal of the present study was to summarize and visualize the knowledge framework, research hotspots, and emerging trends of male osteoporosis research based on the bibliometric method.
    METHODS: Scientific publications regarding male osteoporosis from 1998 to 2020 were downloaded from the SCIE database. VOSviewer, CiteSpace, and online bibliometric website were used for this study. The main analyses include cooperative relationships between countries/institutions/authors, co-citation analysis of authors/journals, and co-occurrence analysis of keywords/subject categories, as well as analyses on keyword/reference bursts.
    RESULTS: A total of 3243 publications with 128,751 citations were identified. Despite experiencing a period of increase in the number of publications, incentives for conducting male osteoporosis research seem to have decreased during recent years. The USA has the most prominent contributions, as reflected by most publications and the highest H-index value. Oregon Health and Science University was the most prolific institution within this domain. The most influential academic journal was Osteoporosis International. Keywords were categorized into four clusters: basic research, epidemiology and risk factors, diagnostic studies, treatment and fracture prevention. Burst keyword detection suggested that the following research directions including "obesity," "zoledronic acid," "DXA," "inflammation," "fall," "microarchitecture," and "sarcopenia" remain research hotspots in the near future and deserve our further attention.
    CONCLUSIONS: This is the first bibliometric analysis that provides a comprehensive overview of male osteoporosis research, which may provide helpful references for investigators to further explore hot issues in this field.

    Dominic Millenaar, Markus Dillmann, Tobias Fehlmann, Alexander Flohr, Roxana Mehran, Rasha Al-Lamee, Lucas Lauder, Christian Ukena, Michael Böhm, Andreas Keller, Felix Mahfoud.
      Background We sought to investigate sex-specific differences in authorship of cardiovascular research over the past decade. Methods and Results All 387 463 cardiovascular publications between 2010 and 2019 were retrieved from Web of Science. Articles increased from 19 960 to 29 604 articles per year (P>0.001). The number of articles written by female first authors increased by 76.3% (6434-11 343 articles) and by 35.0% for male first authors (13 526-18 261) (P<0.001). The first author was more likely to be a female author in articles with female last authors. The median impact factor (IF) for articles by female first authors was lower (2.46 [interquartile range, 7 1.11-4.03] versus 2.51 [interquartile range, 1.17-4.10]; P<0.001). Female authorship articles reached the highest IF in North America (average IF, 3.7), with the lowest in Africa (average IF, 1.8). Conclusions Publications in cardiovascular research have increased over the past decade, particularly by female authors. Female researchers are cited less often compared with their male peers. The IF remains lower for articles by female researchers.

    A bibliometric analysis of international publications and citation trends of articles in mental health produced by Chinese institutions in mainland China (1990-2019).
    Francesca Severino, Valeria Scotti, Tianhong Zhang, Yuchen Zheng, Annalisa De Silvestri.
      Background: The recognition of the importance of mental health as a health-target to be pursued at a global level has received additional theoretical legitimacy through its inclusion in the United Nations (UN) 2030 Agenda for Sustainable development. The theoretical axiom - mental health as a development priority - is today expected to drive the focus of research efforts and orient the future policies and funds expenditures, at global and local level. According to these premises, it becomes central to track the international trajectories of mental health research and how the different countries are progressively defining their role in the global mental health effort. In this paper we have focused on China. In light of heavy burden of mental and substance use disorders affecting this country, and considering the impact of this burden at a global level, a basic research was conducted with the main aim of offering a preliminary view on the Chinese scientific activity within the context of global mental health research. This study is not intended to assess the quality of Chinese research, but merely to retrieve and measure a specific output of this research: the articles in mental-health produced by Chinese institutions based in mainland China, published in international journals. Although the publication of articles in internationally indexed journals in not exhaustive of China's scientific activity in global mental health, it is nevertheless informative of the production of new knowledge, it allows an assessment of the impact of this knowledge at the global scientific community level and it could partially reflect the Chinese capacity to benefit from research conducted globally.Objective: In consideration of the very limited number of studies assessing the collective evidence of Chinese research in mental health, we developed our analysis with the purpose of providing a preliminary picture of the Chinese contribution, in terms of scientific publications, in this field of knowledge. Our research performs a bibliometric analysis on the articles in mental-health produced by Chinese institutions based in mainland China and published in English-language SCI-E and SSCI journals from 1990 to 2019, providing a measure of the impact of this research at the global scientific community level.
    Methods: We performed a search on the Web of Science (WoS) using seven mental and substance use disorders according to their global prevalence, as per estimates of the Global Burden of Disease 2019. A dataset including the overall number of publications for seven diseases was created and exported in InCites. The dataset was analysed on the basis of 11 research areas (WoS categories) to which mental health topic is associated in SCI-E and SSCI journals in WoS. We further extracted publications that originated in mainland China. The citational trends over time are calculated with nonparametric test for trends across ordered groups. An evaluation of the impact of the Chinese scientific production is provided by the number of citations received at the global scientific community level, both as average and percentile.
    Results: From 1990 to 2020 the overall Chinese scientific production in mental health has been generally increasing, reaching the highest growth in the last decade. A statistically significant increase (p < 0.001) is reported for articles produced by Chinese institutions in mainland China regarding 'depression*', 'bipolar disorders*' and 'schizophrenia*'. Published Chinese research is mostly included in SCI-E journals. There is a substantial overlap regarding the average number of citations for articles in mental-health produced by Chinese institutions and the rest of the world. Despite the increasing trend, the percentage of articles in mental health produced by Chinese institutions in mainland China on the overall scientific production worldwide is below 10%.
    Conclusion: Notwithstanding a substantial increase in the last decade, the volume of Chinese publications appears to be very limited, thus resulting in a relatively low impact at a global level. These results are affecting the potential contribution of Chinese research in the global mental health effort.

    The Association Between Professional Accounts on Social Networks Twitter and ResearchGate and the Number of Scientific Publications and Citations Among Anesthesia Researchers: Observational Study.
    Thomas Clavier, Emilie Occhiali, Zoé Demailly, Vincent Compère, Benoit Veber, Jean Selim, Emmanuel Besnier.
      BACKGROUND: Social networks are now essential tools for promoting research and researchers. However, there is no study investigating the link between presence or not on professional social networks and scientific publication or citation for a given researcher.OBJECTIVE: The objective of this study was to study the link between professional presence on social networks and scientific publications/citations among anesthesia researchers.
    METHODS: We included all the French full professors and associate professors of anesthesia. We analyzed their presence on the social networks Twitter (professional account with ≥1 tweet over the 6 previous months) and ResearchGate. We extracted their bibliometric parameters for the 2016-2020 period via the Web of Science Core Collection (Clarivate Analytics) database in the Science Citation Index-Expanded index.
    RESULTS: A total of 162 researchers were analyzed; 42 (25.9%) had an active Twitter account and 110 (67.9%) a ResearchGate account. There was no difference between associate professors and full professors regarding active presence on Twitter (8/23 [35%] vs. 34/139 [24.5%], respectively; P=.31) or ResearchGate (15/23 [65%] vs. 95/139 [68.3%], respectively; P=.81). Researchers with an active Twitter account (median [IQR]) had more scientific publications (45 [28-61] vs. 26 [12-41]; P<.001), a higher h-index (12 [8-16] vs. 8 [5-11]; P<.001), a higher number of citations per publication (12.54 [9.65-21.8] vs. 10.63 [5.67-16.10]; P=.01), and a higher number of citations (563 [321-896] vs. 263 [105-484]; P<.001). Researchers with a ResearchGate account (median [IQR]) had more scientific publications (33 [17-47] vs. 26 [9-43]; P=.03) and a higher h-index (9 [6-13] vs. 8 [3-11]; P=.03). There was no difference between researchers with a ResearchGate account and those without it concerning the number of citations per publication and overall number of citations. In multivariate analysis including sex, academic status, and presence on social networks, the presence on Twitter was associated with the number of publications (β=20.2; P<.001), the number of citations (β=494.5; P<.001), and the h-index (β=4.5; P<.001).
    CONCLUSIONS: Among French anesthesia researchers, an active presence on Twitter is associated with higher scientific publication and citations.

    Factors predictive of an academic otolaryngologist's scholarly impact.
    Courtney B Shires, Theodore D Klug, Ryan K Meacham, Merry E Sebelik.
      Objectives: Describe the h index as a bibliometric that can be utilized to objectively evaluate scholarly impact. Identify which otolaryngology subspecialties are the most scholarly. Describe if NIH funding to one's choice of medical school, residency, or fellowship has any impact on one's scholarly output. Determine other factors predictive of an academic otolaryngologist's productivity.Study design: Analysis of bibliometric data of academic otolaryngologists.
    Methods: Active grants from the National Institutes of Health (NIH) to otolaryngology departments were ascertained via the NIH Research Portfolio Online Reporting Tools Expenditures and Reports database. Faculty listings from these departments were gleaned from departmental websites. H index was calculated using the Scopus database.
    Results: Forty-seven otolaryngology programs were actively receiving NIH funding. There were 838 faculty members from those departments who had a mean h index of 9.61. Otology (h index 12.50) and head and neck (h index 11.96) were significantly (P < 0.0001) more scholarly than the rest of subspecialists. H index was significantly correlative (P < 0.0001) with degree of NIH funding at a given institution. H index was not significantly higher for those that attended medical school (P < 0.18), residency (P < 0.16), and fellowship (P < 0.16) at institutions with NIH funding to otolaryngology departments.
    Conclusions: H index is a bibliometric that can be used to assess scholarly impact. Otology and head and neck are the most scholarly subspecialists within otolaryngology. NIH funding to an individual's medical school, residency, or fellowship of origin is not correlative with one's scholarly impact, but current institutional affiliation and choice of subspecialty are.

    E Can-Güven.
      A bibliometric analysis was conducted to reveal the global status and highlight significant or promising areas of bioaerosol research based on the Web of Science database from 1989 to 2019. Yearly publications, main subject categories, journals, the performance of countries, and research hot topics were identified. The network of keywords and collaborations of countries was visualized and cross relationships were determined. Results showed that the annual output in the field increased during the related period. The USA, China, and Germany are the leading countries while the USA, Germany, and the UK are the most collaborative countries in bioaerosol research. "Journal of Aerosol Science" is the most productive journal and "Environmental Sciences & Ecology" is the most popular research area. The research hot spots are health effects, sampling, particulate matter, and indoor air quality in the bioaerosol topic. The findings of this research could provide information to understand the development and trends as well as future needs of bioaerosol research.

    A bibliometric analysis of mountain ecosystem services, 2000-2019.
    Wenhao Liu, Zengru Wang, Ren Li, Tonghua Wu.
      Research on mountain ecosystem services (MES) under the influence of climate change and human activities has gradually become the focus of academic attention in recent years. Here, this study analyzes the research hotspots and frontiers of this field based on metrics including main research forces, core journals and papers, research hotspots and topics by using the methods of bibliometrics and text mining. The results revealed the following: (1) the number of papers is increasing rapidly in recent years. From 2015 to 2019, 929 papers were published, with an average of 185 papers per year. But the average cited times of those papers is declining, dropped from 6.01 in 2016 to 4.2 in 2019. The USA, UK, and China rank the top three of the number of papers. Univ Maryland, Univ Oxford and Univ Wisconsin have the greatest influence, with an average of more than 77 citations per paper; (2) The most cited journals are PNAS, WETLANDS, ECOLOGY, AND SOCIETY, which are cited 191.54, 53.91, and 40.00 respectively. Most papers were published in OA journals including SUSTAINABILITY, WATER, Forests since 2017. Ten core papers undertaking knowledge transfer in this field have been identified; (3) analysis of the keywords found a new trend of integration of natural science and humanities. In two development stages of 2000-2014 and 2015-2019, the research hotspots mainly focused on mountain water resources, forest resources, land resources and the impact of climate change and human activities, and there are obvious differences and characteristics in different stages. The hotspot worthy of attention in the near future is the assessment of mountain ecosystem services capacity and value. This is the first comprehensive visualization and analysis of the research hotspots and trends of mountain ecosystem services.

    Measuring epistemic success of a biodiversity citizen science program: A citation study.
    Baptiste Bedessem, Romain Julliard, Eleonora Montuschi.
      This paper offers a comparative evaluation of the scientific impact of a citizen science program in ecology, ''Vigie-Nature", managed by the French National Museum of Natural History. Vigie-Nature consists of a national network of amateur observatories dedicated to a participative study of biodiversity in France that has been running for the last twenty years. We collected 123 articles published by Vigie-Nature in international peer-reviewed journals between 2007 and 2019, and computed the yearly amount of citations of these articles between 0-12 years post-publication. We then compared this body of citations with the number of yearly citations relative to the ensemble of the articles published in ecology and indexed in the ''Web of Science" data-base. Using a longitudinal data analysis, we could observe that the yearly number of citations of the Vigie-Nature articles is significantly higher than that of the other publications in the same domain. Furthermore, this excess of citations tends to steadily grow over time: Vigie-Nature publications are about 1.5 times more cited 3 years after publication, and 3 times more cited 11 years post-publication. These results suggest that large-scale biodiversity citizen science projects are susceptible to reach a high epistemic impact, when managed in specific ways which need to be clarified through further investigations.

    An evidence mapping and scientometric analysis of the top-100 most cited clinical trials of anti-PD-1/PD-L1 drugs to treat cancers.
    Ming Liu, Ya Gao, Yuan Yuan, Shuzhen Shi, Jiarui Wu, Jinhui Tian, Junhua Zhang.
      OBJECTIVE: To gain a deeper understanding of the hot topics and future prospects of programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) inhibitors treatment of cancer through scientometric analysis of the top-100 most cited clinical trials.MATERIALS AND METHODS: We searched the Web of Science Core Collection database from 1980 to June 2019. Two reviewers independently screened the top-100 most cited clinical trials that defined by the National Institutes of Health starting from the most cited article. Title, year of publication, citations, type of cancer, and focused aspects of outcomes were extracted from included clinical trials. VOSviewer software (version 1.6.9) and Excel 2016 were used to do statistical analysis. The evidence mapping was used to present the relationship between cancers, drugs, citations, and outcomes, etc. RESULTS: The top-100 most cited clinical trials published from 2010 to 2018 in nine journals with high impact factor (IF) (IF2018:6.68-70.67), and Lancet Oncology (USA) published the most clinical trials (n = 29, IF2018 = 35.3856). The total number of citations of the top-100 most cited clinical trials was from 59 to 5606. 920 authors from 34 countries and 458 organizations participated in publishing the top-100 most cited clinical trials. The USA (n = 95) and Memorial Sloan-Kettering Cancer Center (n = 31) contributed the most publications. Based on the evidence mapping, there are 25 different types of cancers (e.g. lung cancer, melanoma, and renal cell cancer) and five focused aspects of outcomes (e.g. safety and efficacy).
    CONCLUSION: The USA was the dominant country. Anti-PD-1/PD-L1 drugs were widely used to treat lung cancer, melanoma, renal cell cancer, and Hodgkin lymphoma. More exploration should be done to explore the use of anti-PD-1/PD-L1 drugs to treat more type of cancers in future research.

    Abderahman Rejeb, Karim Rejeb, Steven J Simske, John G Keogh.
      Blockchain can function as a foundational technology with numerous applications in smart cities. The objective of this paper is twofold. First, it provides a detailed overview of the extant literature on blockchain applications in smart cities; second, it reveals the trends and suggests future research directions for scholars who wish to contribute to this rapidly growing field. We conducted a bibliometric review using a keyword co-occurrence network and article co-citation analysis. The analysis includes the assessment of 148 articles published between 2016 and 2020 in 76 academic journals. The review results demonstrate that the number of articles devoted to the study of blockchain applications and smart cities has increased exponentially in recent years. More importantly, the research identifies some of the most influential studies in this area. The paper discusses trends and highlights the challenges related to the deployment of blockchain in smart cities. To the authors' best knowledge, this represents the first study to review the literature from leading journals on blockchain applications in smart cities using bibliometric techniques.

    Current research status of cytomegalovirus infection after hematopoietic stem cell transplantation: a bibliometric analysis.
    Peng Chen, Zhenlan Du, Shi Qiu, Haitao Wang, Juan Zhang, Daihong Liu.
      BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is an effective method for the treatment of hematological malignancies, severe aplastic anemia, and myelodysplastic syndromes. The most common infectious complication after HSCT is cytomegalovirus (CMV) infection. The purpose of this study was to analyze the status of research related to CMV infection after HSCT by conducting a literature search for CMV, hematopoietic, and stem cell transplantation.METHODS: The Science Citation Index Expanded (SCI-E) database in the Web of Science Core Collection (WOSCC) was used as the target database for our literature search. The subject search terms were CMV, hematopoietic, and stem cell transplantation, with the logical operation 'AND'. The search date range was from 1900 to June 15, 2021. We used CiteSpace software to analyze the literature. The analysis included: the annual change in the number of publications, the annual change in the number of references cited, the distribution of countries, the distribution of institutions, the distribution of journals, the distribution of authors, and the use of keywords.
    RESULTS: A total of 1,476 relevant documents were retrieved. The top 5 countries for number of publications were the United States, Germany, Japan, China, and Italy, while the top 5 countries for centrality scores were the United States, Australia, Germany, France, and Italy. The top 5 institutions for the number of publications were: Fred Hutchinson Cancer Research Center, the University of Washington, the University of Minnesota, Karolinska Institute, and Peking University. The top 4 institutions for centrality scores were: Fred Hutchinson Cancer Research Center, Henri-Mondor Hospital, the National Cancer Center, Karolinska University Hospital, and the University of Pavia. There were only 4 authors with a centrality score of 0.01. The literature was mainly published in top hematology journals and journals for immunization and transplantation. The top 5 keywords used were: cytomegalovirus, bone marrow transplantation, recipient, infection, and versus host disease.
    CONCLUSIONS: We found that CMV infection after HSCT has been attracting more and more attention by researchers, and that treatment has been the focus of current research.

      BACKGROUND: Total knee arthroplasty (TKA) has brought hope to patients with malignant knee joint diseases. Infection is one of the serious complications after TKA, and the purpose of this study was to use bibliometrics to analyze the current research status of infection after this surgery, to unmask any deficiencies with current research, and to provide references for future researchers.METHODS: We used the Science Citation Index Expanded (SCI-E) database in the Web of Science Core Collection (WOSCC) as the data source, using the search terms "total knee arthroplasty" and "infection" respectively. The "And" operation was performed on the search results of the two subject terms, and the intersection of the two search results was taken as the final search result. CiteSpace software was used to analyze the results.
    RESULTS: The search results consisted of 5,600 documents, with a total citation frequency of 148,871. The average number of citations for each literature was 26.58, and the h-index was 142. The top five countries in the number of publications were the United States, China, Germany, the United Kingdom, and Spain, while the top five centrally ranked countries were the United States, the Netherlands, Germany, the United Kingdom, and France. The top five institutions with the number of publications were Thomas Jefferson Univ, Mayo Clin, Hosp Special Surg, Rush Univ, and Cleveland Clin, while the top institutions for centrality were Thomas Jefferson Univ, Tel Aviv Univ, Univ Melbourne, and Rush Univ. The top five authors of the number of published articles were Parvizi J, Mont MA, Valle CJD, Chen AF, and Hanssen AD, and the top three authors for centrality were Parvizi J, Mont MA, and Valle CJD. The main journals were J Bone Joint Surg Am, Clin Orthop Relat R, J Arthroplasty, J Bone Joint Surg Br, and Int Orthop, and the top five keywords used were total knee arthroplasty, total hip arthroplasty, replacement, infection, and arthroplasty.
    CONCLUSIONS: There is a lack of studies with high-level evidence. The focus of related research in recent years has not changed significantly. More randomized controlled studies are required to provide evidence-based medicine.

    Exploring Topics in Bibliometric Research Through Citation Networks and Semantic Analysis.
    Cristian Mejia, Mengjia Wu, Yi Zhang, Yuya Kajikawa.
      This article surveys topic distributions of the academic literature that employs the terms bibliometrics, scientometrics, and informetrics. This exploration allows informing on the adoption of those terms and publication patterns of the authors acknowledging their work to be part of bibliometric research. We retrieved 20,268 articles related to bibliometrics and applied methodologies that exploit various features of the dataset to surface different topic representations. Across them, we observe major trends including discussions on theory, regional publication patterns, databases, and tools. There is a great increase in the application of bibliometrics as science mapping and decision-making tools in management, public health, sustainability, and medical fields. It is also observed that the term bibliometrics has reached an overall generality, while the terms scientometrics and informetrics may be more accurate in representing the core of bibliometric research as understood by the information and library science field. This article contributes by providing multiple snapshots of a field that has grown too quickly beyond the confines of library science.

      Overviews synthesising the results of multiple systematic reviews help inform evidence-based clinical practice. In this first of two companion papers, we evaluate the bibliometrics of overviews, including their prevalence and factors affecting citation rates and JIF (JIF). We searched MEDLINE, Epistemonikos and Cochrane Database of Systematic Reviews (CDSR). We included overviews that: (a) synthesised reviews, (b) conducted a systematic search, (c) had a methods section, and (d) examined a healthcare intervention. Multivariable regression was conducted to determine the association between citation density, JIF and 6 predictor variables. We found 1218 overviews published from 2000 to 2020; the majority (73%) were published in the most recent 5-year period. We extracted a selection of these overviews (n = 541; 44%) dated from 2000 to 2018. The 541 overviews were published in 307 journals; CDSR (8%), PLOS ONE (3%) and Sao Paulo Medical Journal (2%) were the most prevalent. The majority (70%) were published in journals with impact factors between 0.05 and 3.97. We found a mean citation count of 10 overviews per year, published in journals with a mean JIF of 4.4. In multivariable analysis, overviews with a high number of citations and JIFs had more authors, larger sample sizes, were open access and reported the funding source. An 8-fold increase in the number of overviews was found between 2009 and 2020. We identified 332 overviews published in 2020, which is equivalent to 1 overview published per day. Overviews perform above average for the journals in which they publish. This article is protected by copyright. All rights reserved.

    The Arab Countries' Contribution to the Research of Neurodegenerative Disorders.
    Jad El Masri, Razan Dankar, Diala El Masri, Hani Chanbour, Said El Hage, Pascale Salameh.
      BACKGROUND: Neurodegenerative diseases are disorders in which nerve cells start to lose function due to different causes. Like many other illnesses, they are considered to be highly prevalent in the 22 Arabic-speaking countries known to constitute the Arab world. The two most prevalent neurodegenerative disorders are Alzheimer's disease and Parkinson's disease.AIM: The aim of this paper is to assess the amount of research dedicated to neurodegenerative diseases by the Arab countries during a 15-year period, between 2005 and 2019.
    METHODS: The number of publications by each Arab country as well as some non-Arab speaking countries was retrieved from PubMed. Publications in top 10 neuroscience journals were also tracked using the same method with each journal's name included. The numbers were then normalized with respect to the average population and average gross domestic product (GDP) in each country to eliminate bias.
    RESULTS: Arab countries were shown to contribute only 1,311 (0.774%) of the 169,330 articles published worldwide on neurodegenerative disorders. These 1,311 also constitute only 0.660% of the 198,869 Arab publications during the indicated period. Saudi Arabia had the highest contribution to these numbers with more than one-quarter the number of publications on neurodegenerative disorders. Approximately one-third of all neurodegenerative disease-related articles were associated with Alzheimer's disease, whereas one-fifth were related to Parkinson's disease. For the top 10 neuroscience journals, only a minimal contribution by Arab countries was noted.
    CONCLUSION: Although an increase in the number of articles by the Arab world was noted from 2013 onward, the contribution of the Arab countries on the subject to the number of publications still seems to be insufficient.

    Stakeholder theory and management: Understanding longitudinal collaboration networks.
    Julian Fares, Kon Shing Kenneth Chung, Alireza Abbasi.
      This paper explores the evolution of research collaboration networks in the 'stakeholder theory and management' (STM) discipline and identifies the longitudinal effect of co-authorship networks on research performance, i.e., research productivity and citation counts. Research articles totaling 6,127 records from 1989 to 2020 were harvested from the Web of Science Database and transformed into bibliometric data using Bibexcel, followed by applying social network analysis to compare and analyze scientific collaboration networks at the author, institution and country levels. This work maps the structure of these networks across three consecutive sub-periods (t1: 1989-1999; t2: 2000-2010; t3: 2011-2020) and explores the association between authors' social network properties and their research performance. The results show that authors collaboration network was fragmented all through the periods, however, with an increase in the number and size of cliques. Similar results were observed in the institutional collaboration network but with less fragmentation between institutions reflected by the increase in network density as time passed. The international collaboration had evolved from an uncondensed, fragmented and highly centralized network, to a highly dense and less fragmented network in t3. Moreover, a positive association was reported between authors' research performance and centrality and structural hole measures in t3 as opposed to ego-density, constraint and tie strength in t1. The findings can be used by policy makers to improve collaboration and develop research programs that can enhance several scientific fields. Central authors identified in the networks are better positioned to receive government funding, maximize research outputs and improve research community reputation. Viewed from a network's perspective, scientists can understand how collaborative relationships influence research performance and consider where to invest their decision and choices.

    Gender gaps in National Institutes of Health dermatology grant recipients.
    Alyssa M Thompson, Kyla N Price, Swetha Atluri, Danielle Yee, Jennifer L Hsiao, Vivian Y Shi.
      Background: Understanding the demographics and scholarly merit among National Institutes of Health (NIH) award recipients can help guide future applicants in the field of dermatology.Objective: Herein, we aimed to explore gender gaps in NIH award recipient demographics and scholarly merits for dermatology-related projects.
    Methods: Projects funded by the National Institutes of Arthritis and Musculoskeletal and Skin Diseases between 2015 and 2019 related to dermatology were extracted using the NIH Research Portfolio Online Reporting Tools database. The number of publications and h-index of each award recipient were collected using the Scopus database. The 2019 Blue Ridge Institute for Medical Research report was used to determine the top 20 NIH-funded dermatology departments/divisions.
    Results: Between 2015 and 2019, there were 35.1% more unique male than unique female recipients. Award recipients had an average of 116.7 total publications and an average h-index of 37.1. However, men also had more than half as many publications and a >37% higher average h-index. Gender gaps in research merit, as well as number and type of awards, are reduced among recipients affiliated with a top 20 NIH-funded institution.
    Conclusion: A higher number of awards were granted to male recipients. Men had a higher mean publication number and h-index compared with their female counterparts. Increased support, resources, and mentorship opportunities to women in research may help mitigate these gaps.

    Barriers to cross-disciplinary knowledge flow: The case of medical education research.
    Mathieu Albert, Paula Rowland, Farah Friesen, Suzanne Laberge.
      INTRODUCTION: The medical education research field operates at the crossroads of two distinct academic worlds: higher education and medicine. As such, this field provides a unique opportunity to explore new forms of cross-disciplinary knowledge exchange.METHODS: Cross-disciplinary knowledge flow in medical education research was examined by looking at citation patterns in the five journals with the highest impact factor in 2017. To grasp the specificities of the knowledge flow in medical education, the field of higher education was used as a comparator. In total, 2031 citations from 64 medical education and 41 higher education articles published in 2017 were examined.
    RESULTS: Medical education researchers draw on a narrower range of knowledge communities than their peers in higher education. Medical education researchers predominantly cite articles published in health and medical education journals (80% of all citations), and to a lesser extent, articles published in education and social science journals. In higher education, while the largest share of the cited literature is internal to the domain (36%), researchers cite literature from across the social science spectrum. Findings suggest that higher education scholars engage in conversations with academics from a broader range of communities and perspectives than their medical education colleagues.
    DISCUSSION: Using Pierre Bourdieu's concepts of doxa and field, it is argued that the variety of epistemic cultures entering the higher education research space contributes to its interdisciplinary nature. Conversely, the existence of a relatively homogeneous epistemic culture in medicine potentially impedes cross-disciplinary knowledge exchange.

    Advances of waste management practices in India and China along with bibliometric assessment of their research outcomes.
    Ashu Taneja, Ishwar Dutt, Arun Lal Srivastav.
      This paper presents the progress made by India and China in the field of waste management and its disposal since l996 to 2020. To access it, bibliometric analysis has been carried out using SCOPUS linked SCImago electronic database. Different bibliometric indicators such as documents, citable documents, external and self-citations, and external and self-citations per document along with their annual corresponding growth (ACG) have been calculated in order to explore the progresses made in both the countries. China has contributed 16.3% and India 4.3% to the total documents produced worldwide during 1996-2020 in waste management with the average ACG of 26.42% and 15.37%, respectively, during the same time span. Also, the average ACG for self-citations of published research documents is more than that of external citations for both the countries. In addition to that, the average self-citation magnitude reported for China (28,475) is more than that of India (5223), whereas this trend reverses in the case of average external citation per document with values 16.9 and 28.94, respectively. Moreover, the waste management practices being followed in both countries have also been compared and also presented so that it could be beneficial for the country which is relatively not good in the same.

    Relationship between an editor in chief's commentary publications and the impact factor of cardiovascular medicine journals.
    Alex Salazar, Michael Joseph Berry.
      Journal impact factor (IF) inflation is suggested as a problem resulting from commentaries published by the editors in chief (EiCs) of their respective journals. However, it is unclear whether this is a systemic problem across the top thirty cardiovascular medicine journals. Therefore, the purpose of this investigation was to examine the relationship between the number of commentaries written by an EiC and their journal's IF and Eigenfactor (Ef). Utilizing Spearman rank partial correlations controlling for length of service as the EiC, significant moderate correlations were found between the number of commentaries and the number of first-author commentaries by the EiC and the IF of their journal (r=0.568, p=0.001 and r=0.504, p=0.005; respectively). A weak but still significant correlation was found between the number of commentaries by the EiC and the Ef of their journal (r=0.431, p=0.020). The reason for these correlations is unclear, and whether the methodology used to compute the IF and Ef should be modified needs further research.

    Publication trends related to schizophrenia, mental health, and depression during COVID-19.
    Zalik Nuryana, Ghadah Al Murshidi, Arif Rahman.
      The aim of this article is to analyze publication trends related to schizophrenia, mental health, and depression during COVID-19 in the Asian Journal of Psychiatry. In 2020, 576 articles were identified using bibliometric analysis from scopus.com. According to the results, India had the most articles on schizophrenia, mental health, and depression, followed by China, Australia, Bangladesh, and Japan, during COVID-19. Meanwhile, the most frequently used keywords were schizophrenia (n = 39), COVID-19 (n = 35), mental health (n = 23), depression (n = 22), and adolescents (n = 12). These represent the trend of publications related to the topics discussed in 2020. Moreover, alternative research themes such as life quality, obsessive-compulsive disorder, metabolic syndrome, prevalence, and mental illness can be used in the future.

    Delineating the field of Medical Education: Bibliometric Research Approach (es).
    Lauren A Maggio, Anton Ninkov, Jason R Frank, Joseph A Costello, Anthony R Artino.
      BACKGROUND: The field of medical education remains poorly delineated such that there is no broad consensus of articles or journals that comprise "the field." This lack of consensus indicates a missed opportunity for researchers to generate insights about the field that could facilitate conducting bibliometric studies and other research designs (e.g., systematic reviews) and also enable individuals to identify themselves as "medical education researchers." Other fields have utilized bibliometric field delineation, which is the assigning of articles or journals to a certain field in an effort to define that field.PROCESS: In this Research Approach, three bibliometric field delineation approaches-information retrieval, core journals, and journal co-citation-are introduced. For each approach, the authors describe attempts to apply it in medical education and identify related strengths and weaknesses. Based on co-citation, the authors propose the Medical Education Journal List 24 (MEJ-24), as a starting point for delineating medical education and invite the community to collaborate on improving and potentially expanding this list.
    PEARLS: As a research approach, field delineation is complicated, and there is no clear best way to delineate the field of medical education. However, recent advances in information science provide potentially fruitful approaches to deal with the field's complexity. When considering these approaches, researchers should consider collaborating with bibliometricians. Bibliometric approaches rely on available metadata for articles and journals, which necessitates that researchers examine the metadata prior to analysis to understand its strengths and weaknesses, and to assess how this might affect data interpretation. While using bibliometric approaches for field delineation is valuable, it is important to remember that these techniques are only as good as the research team's interpretation of the data, which suggests that an expanded approach is needed to better delineate medical education, an approach that includes active discussion within the medical education community.

    Mapping the literature of health care management: an update.
    Amber T Burtis, Susan M Howell, Mary K Taylor.
      Objective: This study aims to identify the core journals cited in the health care management literature and to determine their coverage in the foremost bibliographic databases used by the discipline.Methods: Using the methodology outlined by the Medical Library Association's Nursing and Allied Health Resource Section (NAHRS) protocol for "Mapping the Literature of Nursing and Allied Health Professions," this study updates an earlier study published in 2007. Cited references from articles published in a three-year range (2016-2018) were collected from five health care management journals. Using Bradford's Law of Scattering, cited journal titles were tabulated and ranked according to the number of times cited. Eleven databases were used to determine coverage of the most highly cited journal titles for all source journals, as well as for a subset of practitioner-oriented journals.
    Results: The most highly cited sources were journals, followed by government documents, Internet resources, books, and miscellaneous resources. The databases with the most complete coverage of Zone 1 and 2 were Scopus, Web of Science Core Collection, and PubMed, while the worst performing databases were Health Business Elite, ABI/Inform, and Business Source Complete.
    Conclusions: The literature of health care management has expanded rapidly in the last decade, with cumulative citations increasing by 76.6% and the number of cited journal titles increasing by nearly 70% since the original study. Coverage of the core journals in popular databases remains high, although specialized health care management and business databases did not perform as well as general or biomedical databases.

    The use of R in photosynthesis research.
    Yasi Liu, Xiangping Wang, Dayong Fan, Jiangshan Lai.
      R is one of the most commonly used analytical tools in the plant sciences. To identify key trends in general reported R use and patterns in photosynthesis research, we explored the frequency of R use in 2966 articles published in the 377 journals with 'photosynthesis' in the title from 2010 to 2019 using the Web of Science search. Solutions provided by each R package cited in the articles or online sources was recorded and classified. The percentage of research articles reporting R use increased linearly from 3.6% in 2010 to 12.5% in 2019. The three main categories of R package solutions were 'general statistical calculations and graph packages' (G); 'photosynthesis special-purpose packages' (S); and 'genetic and evolutionary packages' (E). The top five R packages cited were nlme (G), lme4 (G), multcomp (G), plantecophys (S), and ape (E). The increasing popularity of R use in photosynthesis research is due to its user-friendly and abundant open-source codes online for handling specific issues, particularly in fitting photosynthesis models. These findings are limited by the number of articles and online sources, but they reveal a significant increase in usage in photosynthesis research over the past decade and have a bright prospect in the future.

    More than seven decades of Acta Tropica: Partnership to advance the 2030 Agenda for Sustainable Development.
    Andrea Graf, Akuto A Konou, Lukas Meier, Norbert W Brattig, Jürg Utzinger.
      The inaugural issue of Acta Tropica has been published in 1944, at a time of utmost international isolation and uncertainty due to World War II. Now, more than seven decades later, Acta Tropica is a trusted outlet to communicate and disseminate scientific advances in the fields of parasitology and tropical medicine. As a scholarly, peer-reviewed journal, Acta Tropica contributes to the 2030 Agenda for Sustainable Development, particularly the Sustainable Development Goal (SDG) 3, that is "Ensure healthy lives and promote well-being for all of all ages". This article explores how Acta Tropica has evolved over time. Our analysis is based on a systematic review of keywords derived from all issues published in a specific year, arbitrarily selected at decadal snapshots (1950, 1960, 1970, 1980, 1990, 2000, 2010, and 2020). Results indicate a decrease in interdisciplinarity in favour of more specialised expertise in various fields of infectious diseases research and public health with a particular emphasis on low- and middle-income countries. Yet, by examining first and last authors' institutional affiliations and classifying countries by the Human Development Index (HDI), we find that most authors are affiliated with institutions in high- and very high HDI countries. Over time, the mean number of authors on a paper has increased severalfold (from 1.35 in 1950 to 7.51 in 2020). Taken together, Acta Tropica has become increasingly globally anchored and contributes not only to SDG 3, but increasingly also to SDG 17, that is "Revitalize the global partnership for sustainable development".

    The impact of article processing charge waiver on conducting research in low-income countries.
    M-Nasan Abdul Baki, Mahmoud Alhaj Hussein.
      Health sciences research is a major tool in exchanging publications and knowledge between the various countries of the world. Researchers in developing countries barely have any financial funding from governmental or educational institutes to support their research. In low-income countries such as Syria, With less than 30$ per month and almost no financial support, Syrian residency doctors are fighting to push the scientific research reality of this ongoing crisis country forward and without a doubt, APC waiver plays a crucial role in this continuing mission.

    Female dermatology journal editors accepting pharmaceutical payments: An analysis of the Open Payments database, 2013 to 2018.
    Waqas Haque, Eman Haque, David Hsiehchen.
      Background: Pharmaceutical payments may affect the interpretation of clinical research and prescribing patterns of physicians. Additionally, they may reflect gender disparities in academic dermatology with regard to social recognition and opportunities for career advancement.Objective: We examined relationships with industry among male and female journal editors who accepted pharmaceutical payments in leading dermatology journals.
    Methods: We assessed the seven US journals among the leading 20 dermatology journals as determined by impact factor and gathered data via the CMS Open Payments dataset.
    Results: In a cross-sectional study of 329 editors eligible to appear in the Open Payments website, we found that 218 (66.3%) received industry payments totaling $21,952,402. The mean and median dollar value of payments per editor was $100,699 and $3,638 (interquartile range, $364-$57,108). Food and beverage payments accounted for 63.0% of the $28,992 total payments, and the associated dollar value was $887,617 (4.04%). Gender disparities in corporate payments were observed in other contexts, but we did not find a similar relationship among leading dermatology journals.
    Conclusion: Our work highlights that pharmaceutical payments exist among dermatology editors, providing a rationale for future research to address whether editor bias related to pharmaceutical payments exists and more granular studies on the role of gender with regard to navigating such payments.

    A review of trends in the development of bionanocomposites from lignocellulosic and polyacids biomolecules as packing material making alternative: A bibliometric analysis.
    Palechor-Trochez Jhon Jairo, Ramírez-Gonzales Gustavo, Villada-Castillo Héctor Samuel, Solanilla-Duque José Fernando.
      Contamination caused by the accumulation of petrochemical-based plastics has reached worrying magnitudes and led to the development of biopolymers as an option to mitigate the problem. This work thus presents a bibliometric analysis of all that concerns the development of such bionanocomposite materials, using ScientoPy and SciMAT software to establish associations between the number of published documents, countries, institutions and most relevant topics. The bionanocomposites topic was found to throw up the biggest number of documents associated (2008) with the different types of raw materials and methods used to obtain nanoparticles and their combination with biopolymeric materials, the result known as a "bionancomposite*". Analysis of the documents related to the application for development of packaging materials from biological molecules, carbohydrate polymers, compounds, conjugates, gels, glucans, hydrogels, membranes, mucilage (source unspecified), mucoadhesives, paper, polymers, polysaccharide, saccharides etc, is also presented, emphasizing mechanical, thermal and barrier properties, which, due to the inclusion of nanoparticles mainly from natural sources of cellulose, show increases of up to 30%. The inclusion of nanoparticles, especially those derived from cellulose sources, generally seeks to increase the properties of bionanocomposite materials. Regarding an increase in mechanical properties, specifically tensile strength, inclusions at percentages not exceeding 10 wt% can register increases that exceed 30% were reported.

      Open-access publishing promotes accessibility to scholarly research at no cost to the reader. The emergence of predatory publishers, which exploit the author-pay model by charging substantial publication fees for publication in journals with questionable publishing processes, is on the rise. Authors are solicited through aggressive marketing tactics, though who is targeted is not well described. The purpose of this study was to identify characteristics associated with critical care pharmacists that make them targets of unsolicited invitations to publish. A prospective, observational study of critical care pharmacists was performed. Participants archived emails received by their professional email that were unsolicited invitations to submit their original work for publication in a journal (unsolicited journals). Variables were evaluated to determine which were associated with unsolicited invitations; these were compared to legitimate journals, defined as all PubMed-indexed journals in which the participants were previously published. Twenty-three pharmacist participants were included, all of whom were residency and/or fellowship trained and practicing in an academic medical center. Participants had a median of 7 years of experience since their post-graduate training, 6 years since their last change in professional email address, and 2 years since their first PubMed-indexed publication. From these participants, 136 unsolicited and 59 legitimate journals were included. The average number of invitations increased 1.04 (95% CI, 1.02-1.05) times for every additional PubMed-indexed publication (P < .001). Most unsolicited journals were considered predatory. Legitimate and unsolicited journals differed significantly. The number of previous PubMed-indexed publications strongly correlates with the likelihood of critical care pharmacists receiving unsolicited publication invitations, often from predatory journal.

    Assessing the Current Research Infrastructure of Pediatric Dentistry Residency Programs: An Update for 2020.
    Nelson Hui, Oscar Arevalo, Apeksha Gupta, Daniel M Saman, Stephen Wilson.
      Purpose: To assess the research infrastructure of pediatric dentistry residency programs in the United States and to determine the variables associated with increased scholarly activity. Methods: A 21-item questionnaire assessing program characteristics, research infrastructure, publication output and grants secured, barriers to scholarly activity, and satisfaction with current research infrastructure was developed and administered to program directors from March through June 2020. Results: Of 94 programs, 43 (46 percent) responded; 22 (51 percent) were hospital-based (H), 15 (35 percent) combined hospital-university-based (C), and six (14 percent) university-based (U). Most programs (77 percent) offered protected time to residents with varying time allocation (P<0.001). Forty-four percent of programs did not offer any protected time for faculty (P=0.001). Median number of faculty publications, resident publications, and grants were highest for U (16, five, and five, respectively) and lowest for H (zero, zero, and zero) (P<0.001; P=0.03; P<0.001). Number of total full-time faculty, full-time board-certified faculty, and full-time faculty with advanced degrees were associated with increased publications and grants secured. Interference with revenue-generating clinical time was the largest barrier to publication. Conclusion: Although university-based programs exhibit the infrastructure most conducive to scholarly activity, these findings suggest pediatric dentistry residency programs may lack resources and infrastructure to generate high quality research.

    Robotic Surgery: At the Crossroads of a Data Explosion.
    Tejinder P Singh, Jessica Zaman, Jessica Cutler.
      BACKGROUND: For the last 20 years, controversies in robotic surgery focused on cost reduction, development of new platforms and technologies, creation and validation of curriculum and virtual simulators, and conduction of randomized clinical trials to determine the best applications of robotics [Leal Ghezzi and Campos in World J Surg 40:2550-2557, 2016].METHODS: This review explores the robotic systems which are currently indicated for use or development in gastrointestinal/abdominal surgery. These systems are reviewed and analyzed for clinical impact in these areas. In a MEDLINE search of articles with the search terms abdominal, gastrointestinal, review and robotic surgery, a total of 4306 total articles as of 2021 were assessed. Publicly available information, highest cited articles and reviews were assessed by the authors to determine the most significant regarding clinical outcomes.
    RESULTS: Despite this increased number of articles related to robotic surgery, ongoing controversies have led to limitation in the use of current and future robotic surgery platforms [Connelly et al. in J Robotic Surg 14:155-165, 2020]. Newer robotic platforms have limited studies or analysis that would allow meaningful definite conclusions. A multitude of new scenarios are possible due to this limited information.
    CONCLUSION: Robotic surgery is in evolution to a larger conceptual field of computationally enhanced surgery (CES). Various terms have been used in the literature including computer-assisted surgery or digital Surgery [Ranev and Teixeira in Surg Clin North Am 100:209-218, 2020]. With the growth of technological changes inherent in CES, the ability to validate these improvements in outcomes will require new metrics and analytic tools. This learning feedback and metric analysis will generate the new opportunities in simulation, training and application [Julian and Smith in Int J Med Robot 15:e2037, 2019].

    Demystifying COVID-19 publications: institutions, journals, concepts, and topics.
    Haihua Chen, Jiangping Chen, Huyen Nguyen.
      Objective: We analyzed the COVID-19 Open Research Dataset (CORD-19) to understand leading research institutions, collaborations among institutions, major publication venues, key research concepts, and topics covered by pandemic-related research.Methods: We conducted a descriptive analysis of authors' institutions and relationships, automatic content extraction of key words and phrases from titles and abstracts, and topic modeling and evolution. Data visualization techniques were applied to present the results of the analysis.
    Results: We found that leading research institutions on COVID-19 included the Chinese Academy of Sciences, the US National Institutes of Health, and the University of California. Research studies mostly involved collaboration among different institutions at national and international levels. In addition to bioRxiv, major publication venues included journals such as The BMJ, PLOS One, Journal of Virology, and The Lancet. Key research concepts included the coronavirus, acute respiratory impairments, health care, and social distancing. The ten most popular topics were identified through topic modeling and included human metapneumovirus and livestock, clinical outcomes of severe patients, and risk factors for higher mortality rate.
    Conclusion: Data analytics is a powerful approach for quickly processing and understanding large-scale datasets like CORD-19. This approach could help medical librarians, researchers, and the public understand important characteristics of COVID-19 research and could be applied to the analysis of other large datasets.
